What was the last kernel version you were using that didn't show the issue? Couple of things to try below: > dmesg: > Linux version 2.6.23 ([EMAIL PROTECTED]) (gcc version 4.2.1 (Gentoo 4.2.1 > p1.0)) #1 Fri Oct 12 16:55:58 EDT 2007 > ACPI: RSDP 000FEC00, 0014 (r0 DELL ) > ACPI: RSDT 000FCC05, 0040 (r1 DELL GX280 7 ASL 61) > ACPI: FACP 000FCC45, 0074 (r1 DELL GX280 7 ASL 61) > ACPI: DSDT FFFD060C, 30BF (r1 DELL dt_ex 1000 MSFT 100000D) > ACPI: FACS 1F686C00, 0040 > ACPI: SSDT FFFD3808, 00BA (r1 DELL st_ex 1000 MSFT 100000D) > ACPI: APIC 000FCCB9, 0072 (r1 DELL GX280 7 ASL 61) > ACPI: BOOT 000FCD2B, 0028 (r1 DELL GX280 7 ASL 61) > ACPI: ASF! 000FCD53, 0067 (r16 DELL GX280 7 ASL 61) > ACPI: MCFG 000FCDBA, 003E (r1 DELL GX280 7 ASL 61) > ACPI: HPET 000FCDF8, 0038 (r1 DELL GX280 7 ASL 61) > ACPI: PM-Timer IO Port: 0x808 > ACPI: HPET id: 0x8086a201 base: 0xfed00000 > Kernel command line: root=/dev/sda2 > Initializing CPU#0 > Detected 2660.302 MHz processor. > hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0 > hpet0: 3 64-bit timers, 14318180 Hz > Calibrating delay using timer specific routine.. 5324.67 BogoMIPS > (lpj=10649351) > CPU: After generic identify, caps: bfebfbff 00100000 00000000 00000000 > 0000451d 00000000 00000000 00000000 > monitor/mwait feature present. > using mwait in idle threads. > CPU: Trace cache: 12K uops, L1 D cache: 16K > CPU: L2 cache: 256K > CPU: After all inits, caps: bfebfbff 00100000 00000000 0000b180 > 0000451d 00000000 00000000 00000000 > Intel machine check architecture supported. > Intel machine check reporting enabled on CPU#0. > CPU0: Intel P4/Xeon Extended MCE MSRs (12) available > CPU: Intel(R) Celeron(R) CPU 2.66GHz stepping 01 > Checking 'hlt' instruction...

Could you disable CONFIG_HANGCHECK_TIMER in your .config?

Another thing to try: Boot with "clocksource=hpet" and verify that avoids or triggers the issue. If it triggers the issue does it go away with "clocksource=acpi_pm"? thanks -john - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
